Hello :

I have some trouble copying a string from program memory to data memory.
Sometimes it works ok, sometimes one byte is wrong, sometimes all the string
is wrong.
This is my code written for mcc18 compiler:

char *pointer_RAM;
char rom *pointer_ROM;

pointer_RAM = buffer_TX_USART; // buffer in data memory
pointer_ROM = Comandos_Tc35 [comando]; // string in rom

  while (INTCONbits.GIE == 1) INTCONbits.GIE = 0; // Disable int
  while ( (*pointer_RAM++ = *pointer_ROM++) != 0x00);
  while (INTCONbits.GIE == 0) INTCONbits.GIE = 1; // Enable int

Any ideas?
Should I write this piece of code in asm?
Carlos.
